//1.table的逻辑
//table数据
const tabelData = ref<reqTrademarkReturnRecordsType>([]);

//2.页码逻辑
//页码的数据和类型
interface pageDateType {
  page: number;

  total: number;

const pageDate = ref<pageDateType>({
  page: 1,
  limit: 3,

//3.获取品牌列表
//封装获取品牌列表的功能函数

  dialogFormVisible.value = true;

    value是当前需要被检验的值
